Acid

No pun intended - the movie is a bit slow paced, but still has quite the impact. I had no idea this was based on a short movie (I probably would have watched it prior if I had known) ... just saw this on the site here. I assume the general idea was taken and expanded - more time to tell the story. But maybe it works or rather worked, better in the shorter format.

Acting is fine, the effects are good and the movie does look good. Not sure about the ending myself, but things have to end one way or another - overall the movie does not seem to get too much love here - but it is more than decent of course. Just be aware that this demands patience from you the viewer.
